Experimenta circa effectum conflictus electrici in acum magneticam
FIRST PUBLISHED EDITION of one of the rarest and most important papers of modern science: Oersted's discovery of the connection between electricity and magnetism. Preceded only by the legendarily rare privately-printed pamphlet (of which only a few copies are known to exist, only one in private hands), the first journal printing is exceedingly scarce. Text in the original Latin."The 'Experimenta...' opened a new epoch in the history of physics. From it followed the creation of electrodynamics by Ampere and Faraday's 'Experimental Researches in Electricity" (DSB)."It was after lecturing to students in his own rooms in the Noerragade, Copenhagen, in 1819 or 1820 that [Oersted] invited a few of them to stay on to witness an experiment- the possible deflection of a compass -needle by an adjacent electric current. The experiment was successful; but only just; and Oersted repeated it many times before venturing on 21 July to proclaim the identity of magnetism and electricity in this four-page paper entitled 'Experiments relative to"The 'Experimenta...' opened a new epoch in the history of physics. From it followed the creation of electrodynamics by Ampere and Faraday's 'Experimental Researches in Electricity" (DSB). the Effect of the Contiguity of Electricity to a Magnetic Needle'."The results were as important as they were widespread. Oersted's paper was within the year reprinted in England, France, Germany, Italy and Denmark. In 1823 Ronalds and in 1833 Gauss and Weber constructed the first practical electric telegraphs. Faraday's momentous experiments with the sequels by Clerk Maxwell, Hertz and others bore further witness to its significance" (Printing and the Mind of Man, 282).Printed in the July, 1820 issue of Schweigger's Journal für Chemie und Physik. Less than a year later, "in 1821, volume 31 of the prestigious Journal für Chemie und Physik opened with an editorial announcing a change in format 'in part because a new epoch in chemistry and physics appears to have begun with Ørsted's important discoveries on the connection between magnetism and electricity.' A contributor wrote: 'Orsted's experiments regarding magnetism are the most interesting ones performed in more than a thousand years'" (Physics in Denmark, nobelprize.org).WITH: Neuere electro-magnetische Versuche, Oersted's succeeding paper on the interactions between an electric current and a magnetic field. In: Journal für Chemie und Physik. Hrsg. v. Schweigger u. Meinecke, Vol. 29, pp. 275-281 (Oersted in July issue); Neuere electro-magnetische Versuche, pp. 364-369. Nuremberg: Schrag, 1820. The whole volume offered. Octavo, contemporary three-quarter green morocco, marbled boards. Some wear to edges of binding, text clean. Provenance: with library and de-accession stamps on series title from the prestigious Gmelin Institute (after 1996, part of the Max Planck Institute). SCARCE.
